BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to patient mask supply junctions and more particularly pertains to a new patient mask supply junction for administering nebulizer treatments directly to a supply of oxygen supplied to a patient mask.

2. Description of the Prior Art

The use of patient mask supply junctions is known in the prior art. The prior art commonly teaches a patient mask having several connections to allow multiple treatment machines to be coupled to the patient mask and thus uses the patient mask to mix treatments provided from the treatment machines.

While these devices fulfill their respective, particular objectives and requirements, the need remains for a device that has certain improved features that allow treatments from a nebulizer to be provided directly to a supply of oxygen supplied to a patient mask prior to the oxygen supply reaching the patient mask. Additionally, the nebulizer may be positioned at a variety of angles to enhance the comfort of a patient wearing the patient mask.

SUMMARY OF THE INVENTION

The present invention meets the needs presented above by generally comprising a supply conduit being couplable to an oxygen supply and a patient mask to allow oxygen from the oxygen supply to be supplied to the patient mask. A side conduit is coupled to and is in fluid communication with the supply conduit. The side conduit extends substantially orthogonal to the supply conduit. An elbow conduit is rotatably coupled to the side conduit opposite the supply conduit. The elbow conduit is couplable to a nebulizer to permit treatments from the nebulizer to flow through the elbow conduit and the side conduit into the oxygen being supplied to the patient mask. A valve assembly is positioned in the elbow conduit between the side conduit and the nebulizer. The valve assembly opens to permit the treatments from the nebulizer to flow into the elbow conduit when air pressure from the nebulizer is greater than an air pressure in the supply conduit. The valve assembly closes to inhibit the treatments from entering the elbow conduit when the air pressure in the supply conduit is greater than the air pressure from the nebulizer.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 3 thereof, a new patient mask supply junction embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 3, the junction device 10 generally comprises a supply conduit 12 being couplable to an oxygen supply 1 and a patient mask 2 to allow oxygen from the oxygen supply 1 to be supplied to the patient mask 2. The supply conduit 12 includes a first end 14 being received by the oxygen supply 1. The supply conduit 12 includes a second end 16 positioned opposite the first end 14. The second end 16 receives an inlet port 3 of the patient mask 2 to allow oxygen supplied to the supply conduit 12 to be supplied to a patient wearing the patient mask 2.

A side conduit 18 is coupled to and is in fluid communication with the supply conduit 12. The side conduit 18 extends substantially orthogonal to the supply conduit 12. The side conduit 18 is positioned between the first end 14 and the second end 16 of the supply conduit 12. The side conduit 18 includes a flange 20 being coextensive and extending outwardly from a free end 22 of the side conduit 18.

An elbow conduit 24 is rotatably coupled to the side conduit 18 opposite the supply conduit 12. The elbow conduit 24 is couplable to a nebulizer 4 to permit treatments from the nebulizer 4 to flow through the elbow conduit 24 and the side conduit 18 into the oxygen being supplied to the patient mask 2. The elbow conduit 24 includes a first portion 26 rotatably coupled to the free end 22 of the side conduit 18 to permit rotational adjustment of the elbow conduit 24 with respect to the side conduit 18. The first portion 26 is axially aligned with the side conduit 18. The first portion 26 includes a flange collar 28 for receiving and extending around the flange 20 of the side conduit 18 to rotatably couple the elbow conduit 24 to the side conduit 18.

The elbow conduit 24 also includes a seal 30 positioned between the flange 20 of the side conduit 18 and the flange collar 28 of the elbow conduit 24. The seal 30 inhibits fluid communication between an environment and the treatments passing through the elbow conduit 24 and the side conduit 18. A second portion 32 is coupled to the first portion 26 opposite the side conduit 18. The second portion 32 extends substantially orthogonal to the first portion 26. A receiving collar 34 is coupled to the second portion 32 opposite the first portion 26. The receiving collar 34 receives the nebulizer 4 to selectively mount the nebulizer 4 to the elbow conduit 24 and permit treatments to be supplied to the elbow conduit 24.

The elbow conduit 24 additionally includes a cap 36 couplable to the receiving collar 34 to selectively close the receiving collar 34 when the nebulizer 4 is removed from the receiving collar 34. A tether 38 is coupled to the cap 36 and extends around the second portion 32. The tether 38 inhibits loss of the cap 36 when the cap 36 is removed from the receiving collar 34.

A valve assembly 40 is positioned in the elbow conduit 24 between the side conduit 18 and the nebulizer 4. The valve assembly 40 opens to permit the treatments from the nebulizer 4 to flow into the elbow conduit 24 when air pressure from the nebulizer 4 is greater than an air pressure in the supply conduit 12. The valve assembly 40 closes to inhibit the treatments from entering the elbow conduit 24 when the air pressure in the supply conduit 12 is greater than the air pressure from the nebulizer 4.

The valve assembly 40 includes a partition wall 42 coupled to the second portion 32 and extending across a bore 44 of the elbow conduit 24. The partition wall 42 has a treatment aperture 46 permitting the treatments from the nebulizer 4 to pass through the partition wall 42. The partition wall 42 is positioned adjacent the receiving collar 34. A base wall 48 is coupled to the second portion 32 and is positioned in the bore 44 of the elbow conduit 24. The base wall 48 is positioned adjacent the first portion 26.

The valve assembly 40 also includes a biasing member 50 coupled to the base wall 48 and extends towards the partition wall 42. A closure member 52 is coupled to the biasing member 50 opposite the base wall 48. The closure member 52 is biased into the treatment aperture 46 of the partition wall 42 to close the treatment aperture 46 when the air pressure in the supply conduit 12 is greater than the air pressure from the nebulizer 4. The closure member 52 is forced out of the treatment aperture 46 to open the treatment aperture 46 to allow treatments to pass through the partition wall 42 when the air pressure from the nebulizer 4 is greater than the air pressure in the supply conduit 12.

In use, the oxygen supply 1 is coupled to the first end 14 of the supply conduit 12 and the patient mask 2 to the second end 16. The nebulizer 4 is coupled to the receiving collar 34 of the elbow conduit 24 to receive treatments from the nebulizer 4. The valve assembly 40 opens to allow the treatments from the nebulizer 4 to flow into the elbow conduit 24 and into the supply conduit 12 when the air pressure in the supply conduit 12 is reduced by the patient inhaling. The valve closes to inhibit introduction of the treatments into the elbow conduit 24 when the patient exhales and the air pressure in the supply conduit 12 is greater than the air pressure from the nebulizer 4.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
